Higosoft Free YouTube Downloader for Mac is a free video downloader. It can be used to download videos from YouTube.com and save them on your computer to later play them on any player that supports playback of MP4 files. This downloader follows the same approach as many other downloaders. It asks you to provide the URL of the video that you want to download. All you really have to do is go to YouTube.com on your web browser and find a video that you want to download. Then you can copy the URL from the address bar, and click on "Paste URL" on the application's main window. By default, whenever you add a download, a new window will pop-up, which will ask you what quality of the video you want to download, and where you want to save the file. The quality options are: best quality, optimal parameters and minimal size.
Graphically, this downloader looks identical to other free converters that I have tried in the past. I don't really mind that because it is free and it works really well.
The two videos that I downloaded with this app looked very good and I could play them on QuickTime without any problems.
